Ramp Metering Control的意思|示意

Ramp metering is regarded as one of the best control strategies for freeway traffic system and is widely used.

在高速公路控制方法中，入口匝道控制是应用最广、效果最好的一种控制方法。

Due to the traits of nonlinear, capacity of study, adaptivity and anti-interference, neural-fuzzy network is suitable for the control of ramp metering.

鉴于模糊神经网络具有良好的非线性特性、学习能力、自适应能力和抗干扰能力，本文将模糊神经网络技术引入到高速公路入口匝道控制中。

Once surface street service level is (unacceptable) because of traffic diversion caused by ramp control, either the metering rate will be modified or the (on-ramp) will be closed.

当因交通分流导致地面道路服务水平不可接受时，采取修正调节率或者关闭匝道的措施。

An optimal control model of on-ramp metering was constructed, which was based on the dynamic discrete traffic flow model in multilane freeway.

建立了一个基于多车道动态离散交通流模型的高速公路入口匝道流量优化控制模型。

When the traffic demand is too high that ramp metering is not effective anymore, the variable speed limit control is needed to relieve the congestion.

但是当高速公路严重拥挤时，匝道控制不再有效，需结合主线可变限速控制，以缓解交通拥挤。

Therefore, an effective combination of ramp metering and variable speed limit control is important to achieve a good performance.

由此，匝道调节率与可变速度限制间高效的联合控制对于提高道路性能显得尤为重要。
